Ongoing Mineral Exploration Programmes


INVESTIGATION OF BUNDELKHAND QUARTZ
REEF IN SELECTED AREAS OF JHANSI & MAHOBA
DISTRICTS FOR ITS COMMERCIAL USES.

                

GEOLOGY

The Bundelkhand granitic massif, covering an area of about 26,000 sq km in Southwestern part of Uttar Pradesh and Northeastern Madhya Pradesh in Central India, forms the Northern fringe of the peninsular Indian shield.
 

Quartz reefs, the most spectacular landmarks in the Bundelkhand granitic massif are NE-SW, N-S, and NW-SE trending ridges of about 20-80m high above the surrounding country. Among them N-S, NW-SE trending quartz reefs show sulphide mineralization. Two sets of milky white secondary quartz veins are also present in almost all reefs. First set follows the regional trend of quartz reefs. Another set of vein is trending towards NNW-SSE direction.
 

Dolerite dyke are very common in Bundelkhand massif and probably mark the last phase of intrusive activity. Majority of the dykes trending NW-SE direction cuts across the NE-SW trending quartz reefs. Most of the dykes are discontinuous and follow en echelon fractures.

 

ACHIEVEMENTS

Chemical analysis of quartz reefs of Mondkhurd / Mondkalan, Gulara, Dharampur, Seemrabari, Rasoi, Harpalpur, Gopalpur, Khajraha areas of district Jhansi consist of average Si02: 85-99%, A1203 : 2-15%, Fe203: 0.1-1%, CaO : 0.1-0.5%, MgO : 0.1-0.5%. On the basis of chemical analyses, these quartz reefs may be commercially viable in different industries.
